TO 土老帽:
Yb-{+H8{ J &oMWs]0 1) Before you use any software, you'd better read some theoretical
e*qGrg (E %s"& |32 books about finite element method for structure, for example the
Q&N#q 53 W^H3 =hZ book from Tsinghua Univ. is good one.
(w#t V* |4g0@}nr+W 2) After you understand the FEM in structures(beam or truss),
(De{r| /W)A[jR you can use some small finite element program to
]VxC] a2 HO['o{>BL solve beam or some structure problems for better understanding;
